I can go with the reasoning for the opt in for MAB, but disabling link
local learning system wide I don't think is a good idea, unless
someone can ensure me that it does not impact something else.
In general locked ports should never learn from link local, which is a
problem if they do, which suggests to me that this patch should
eventually be accepted as the best solution.
